The explicit symplectic integrator for the separable Hamiltonian straightforwardly leads to generalization of the splitting scheme for the Vlasov-Poisson system. The Nth-order version improves the total energy conservation decreasing the error as propto Delta t^N where Deltat denotes the time step size. An Eulerian drift kinetic simulation scheme derived from the implicit symplectic integrator for the non-separable Hamiltonian exactly satisfies the conservation of the energy and the enstrophy in the K-H instability, and results in successful application to the plasma echo.","subitem_description_type":"Abstract"}]},"item_5_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-633X","subitem_source_identifier_type":"ISSN"}]},"item_5_text_8":{"attribute_name":"報告書番号","attribute_value_mlt":[{"subitem_text_value":"NIFS-792"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Watanabe,  T.-H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sugama,  H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-03-11"}],"displaytype":"detail","filename":"NIFS-792.pdf","filesize":[{"value":"621.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NIFS-792.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/10403/files/NIFS-792.pdf"},"version_id":"9ec4c2ea-73cc-4f86-99f7-506bdaca8675"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Vlasov simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"drift kinetic simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"symplectic integrator","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"simulation method","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"Vlasov and Drift Kinetic Simulation Methods Based on the Symplectic Integrator","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Vlasov and Drift Kinetic Simulation Methods Based on the Symplectic Integrator","subitem_title_language":"en"}]},"item_type_id":"5","owner":"3","path":["32"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"10403","relation_version_is_last":true,"title":["Vlasov and Drift Kinetic Simulation Methods Based on the Symplectic Integrator"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:42:45.351455+00:00"}
